copied!<p>A few moments ago I had a similar problem - a standard MFC menu bar containing at least one submenu, and the need to be able to add a check mark to the <em>submenu</em> parent item, when any of the submenu <em>child</em> items were checked.</p> <p>The easiest solution (for me) turned out to be as simple as performing the update in the standard OnUpdateMenuItem(CCmdUI* pCmdUI) call. In my case I used ON_UPDATE_COMMAND_UI_RANGE() to feed a bunch of menu IDs into the same update call, but the principal is the same for a single ON_UPDATE_COMMAND_UI() map.</p> <p>The code I used (edited to be more easily inserted into other people's work) is:</p> <pre><code>void CMyApp::OnUpdateMenu(CCmdUI* pCmdUI) { // Note, a submenu parent (which has no editable ID in the resource editor) has the SAME ID as the first child item if (pCmdUI->m_nID == ID_FIRST_CHILD_MENU && pCmdUI->m_pSubMenu != NULL) { // Get the child menu so we can see if any child items are checked CMenu* pSubMenu = pCmdUI->m_pSubMenu; BOOL fChildChecked = FALSE; for (UINT i = 0; !fChildChecked && i < pSubMenu->GetMenuItemCount(); ++i) { // Do something to decide if this child item should be checked... UINT nChildID = pSubMenu->GetMenuItemID(i); fChildChecked = IsThisChildChecked(nChildID); } // The POSITION of the current menu item is stored in pCmdUI->m_nIndex CMenu* pMenu = pCmdUI->m_pMenu; UINT flags = MF_BYPOSITION; if (fActiveChild) flags |= MF_CHECKED; pMenu->CheckMenuItem(pCmdUI->m_nIndex, flags); } // Set the enabled state of the menu item as you see fit... pCmdUI->Enable(TRUE); } </code></pre> <p><em>Et voilà</em> the submenu item automagically gains a check mark when any of its child menu items has a check mark.</p> <p>Hope this helps others looking for similar solutions!</p> <p>John</p>
